This is a great idea. I find LLMs to be a good teacher, though I've primarily interacted with them through text.

I'm curious, what are the economics of producing this longer form content?

Thank you!

Actually, the economics are quite good.

We’re not using video generation models. We ask an LLM to write the lecture as code, then render it deterministically with computer graphics and TTS.

So the main costs are the LLM call, TTS, and some cloud GPU time for rendering. That ends up being much cheaper than generating long form video directly with video models.
